动词过去式详解 动词的过去式的构成规则有:

A、规则动词

① 一般直接在动词的后面加ed:如 worked , learned , cleaned , visited

② 以e结尾的动词直接加d:如 lived , danced , used

③ 以辅音字母加y结尾的动词要改y为i再加ed(此类动词较少)如 study – studied carry – carried worry – worried (注意play、stay不是辅音字母加y,所以不属于此类)

④ 双写最后一个字母(此类动词较少)如 stopped

B、不规则动词(此类词并无规则,须熟记)小学阶段要记住以下动词的原形和过去式:sing – sang , eat – ate ,

③ 双写最后一个字母的(此类动词极少)有:running , swimming , sitting , getting

英语语法动词时态详解 篇三

时态是一种语法范畴,是用以表示各种时间和动作方面的动词形式。

谓语动词的时态决定了整句的时态。

时间有四个主要部分,即现在,过去,将来和过去将来。动作方面也有四种,即一般,完成,进行和完成进行。将这些时间与动作方面组合在一起,即构成16种时态。如下:

现在 : 一般现在时 I work

现在完成时 I have worked

现在进行时 I am working

现在完成进行时 I have been working

过去 : 一般过去时 I worked

过去完成时 I had worked

过去进行时 I was working

过去完成进行时 I had been working

将来时态: 一般将来 I shall work

将来完成 I shall have worked

将来进行 I shall be working

将来完成进行 I shall have been working

过去将来 : 一般过去将来 I should work

过去将来完成 I should have worked

过去将来进行 I should be working

过去将来完成 I should have been working

四个动作方面各有其特点,现在分述如下:

1.一般方面:

用以叙述一单纯事实,时间可以不具体

动态动词的一般方面常表动作已经完成。

2.完成反面

用以表达一个动作已经完成

身夸两个时间,动作发生于前一个时间。但说话人的兴趣一般在后一个时间

3.进行方面

表示动作在一时段进行,说话人的兴趣一般不在动作何时开始,何时结束。而在于他所关心的时点上。

往往是提出一种情景,故描述性强,比较生动。

4.完成进行方面

兼有完成与进行两个方面的特点也有夸两个时间,但二者往往相距不远。

动词的四种时态 篇四

不及物动词不能用于被动语态

如appear,rise,die,happen,belong to,break out,take place等。

Great changes have been taken place in my hometown.(误)

Great changes have taken place in my hometown. (正)

我们家乡发生了巨大的变化。

表示状态的动词不用于被动语态

如lack,fit,mean,hold,have,cost,contain,become,last,possess,consist of,look like等。

The book costs 10 yuan.这本书花了10元钱。

What’s become of her?她怎么了?

主动形式表被动的几种情况

(1)某些感官动词和系动词后加形容词可以表示被动意义,如look,smell,taste,feel,prove,wear,sound等。

The flower smells sweet.花闻起来很香。

The dish tastes delicious.菜吃起来非常可口。

(2)在主语是物的句子里,有些动词的主动形式可以表示被动意义,这些词后常有副词修饰。常用的这类动词有

sell,read,write,wear,wash,open,clean,cook,keep,cut,fill,blow,measure,lock,run,record,begin,shut等。

This type of recorder sells well.

这种型号的录音机销路很好。

H e doesn’t photograph well.他不太上相。

This kind of shirt cleans easily.这种衬衫容易洗干净。

(3)动名词主动形式表示被动意义

通常是事物(也可以是人)作want,need, require,deserve等动词的主语时,表示事物(或人)客观上“需要……”,用动名词一般式的主动形式作宾语表示被动意义。若动名词是不及物的,后面还应有相应的介词。

The children need looking after.孩子们需要照看。

这种用法还可把动名词改为动词不定式的被动形式来表被动。

The children need to be looked after.

(4)在作表语的某些形容词(easy,difficult,light,heavy,fit,good,safe,comfortable,dangerous,pleasant等)后作状语用的不定式用主动形式表示被动意义。

She is easy to approach.她平易近人。

The rock is hard to break.这块岩石很难打碎。

不定式符号to在被动语态中不可省略

在主动语态中,如果感官动词和使役动词后的宾语补足语是动词,这个动词前往往不用to,但在被动语态中要带to。

I saw her pass by the window.我看见她从窗边经过。

She was seen to pass by the window.她被看见从窗边经过。

get (got)+过去分词也可构成被动语态

get常同marry,beat,break,damage,tear,strike,hurt,paint,invite,repair,dress等动词的过去分词连用,构成被动语态。

上个月,约翰和简结婚了。

They got caught in the storm.他们碰上暴风雨了。

英语语法动词时态详解 篇五

一、概念:

时态是英语谓语动词的一种形式,表示动作发生的时间和所处的状态。英语中的时态是通过动词形式本身的变化来实现的。英语有16种时态,但中学阶段较常用的有十种:一般现在时,一般过去时,一般将来时,过去将来时,现在进行时,过去进行时,将来进行时,过去完成时,英在完成时和现在完成进行时。

二、相关知识点精讲

1.一般现在时的用法

1) 经常性或习惯性的动作,常与表示频腮度的时间状语连用。时间状语: every…, sometimes, at…, on Sunday.例如:

I leave home for school at 7 every morning. 每天早上我七点离开家。

2) 客观真理,客观存在,科学事实。例如:

The earth moves around the sun. 地球绕太阳转动。

Shanghai lies in the east of China. 上海位于中国东部。

3) 表示格言或警句。例如:

Pride goes before a fall. 骄者必败。

注意:此用法如果出现在宾语从句中,即使主句是过去时,从句谓语也要用一般现在时。

例:Columbus proved that the earth is round. 哥伦布证实了地球是圆的。

4) 现在时刻的状态、能力、性格、个性。例如:

I don't want so much. 我不要那么多。

Ann writes good English but does not speak well. 安英语写得不错,讲的可不行。

比较:Now I put the sugar in the cup. 把糖放入杯子。

I am doing my homework now. 我正在做功课。

第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用一般现在时。

2. 一般过去时的用法

1)在确定的过去时间里所发生的动作或存在的状态。例如:时间状语有:yesterday, last week, an hour ago, the other day, in 1982等。例如:

Where did you go just now? 刚才你上哪儿去了?

2)表示在过去一段时间内,经常性或习惯性的动作。例如:

When I was a child, I often played football in the street. 我是个孩子的时候,常在马路上踢足球。

Whenever the Browns went during their visit, they were given a warm welcome.

那时,布朗一家无论什么时候去,都受到热烈欢迎。

3)句型:It is time for sb. to do sth “到……时间了” “该……了”。例如:It is time for you to go to bed. 你该睡觉了。

It is time that sb. did sth. “时间已迟了” “早该……了” ,例如It is time you went to bed. 你早该睡觉了。

would (had) rather sb. did sth. 表示'宁愿某人做某事'。例如:I'd rather you came tomorrow.还是明天来吧。

4) wish, wonder, think, hope 等用过去时,作试探性的询问、请求、建议等,而一般过去时表示的动作或状态都已成为过去,现已不复存在。例如:

I thought you might have some.我以为你想要一些。

比较:Christine was an invalid all her life.(含义:她已不在人间。)

Christine has been an invalid all her life.(含义:她现在还活着)

Mrs. Darby lived in Kentucky for seven years. (含义:达比太太已不再住在肯塔基州。)

Mrs. Darby has lived in Kentucky for seven years. (含义:现在还住在肯塔基州,有可能指刚离去)

注意: 用过去时表示现在,表示委婉语气。

1)动词want, hope, wonder, think, intend 等。例如:

Did you want anything else? 您还要些什么吗?

I wondered if you could help me. 能不能帮我一下。

2)情态动词 could, would.例如:

Could you lend me your bike? 你的自行车,能借用一些吗?

3.一般将来时

1) shall用于第一人称,常被will 所代替。will 在陈述句中用于各人称,在征求意见时常用于第二人称。例如:

Which paragraph shall I read first? 我先读哪一段呢?

Will you be at home at seven this evening? 今晚七点回家好吗?
